Efficiency of copper removal by Sargassum sinicola in batch and continuous systems

The efficiency of batch and continuous systems of copper removal by Sargassum sinicola was studied. The effects of flow rate, initial metal concentration, and bed density on the capacity of the continuous system were also recorded. In batch systems, the maximum biosorption capacity was calculated as 49.63 ± 0.88 mg g−1; in the continuous system, under the following conditions: flow rate of 10 mL min−1, initial solution of 200 mg Cu L−1, bed density of 150 g L−1, and higher copper removal of 62.39 ± 1.91 mg g−1 was achieved. The Thomas model can be used to predict the breakthrough curves, but it underestimated breakthrough time.
